Title: Improvements in and relating to fluid valves
Inventor: GREENE GEORGE BOYD
IPC: F15C3/00
Filed: 1968-06-11
Abstract: 1,217,538. Bail valves. ELECTRONIC ENG. CO. OF CALIFORNIA. 11 June, 1968, No. 27626/68. Heading F2V. [Also in Division G4] A bail valve for fluid operated data processing and process control devices comprises tubular actuating member 10, whose ends are fluidtightly joined to coil springs 11, 12 also fluidtightly joined to stems 15, 16 of which 15 is closed at the outer end while 16 is tubular and connected over flexible tube 18 to a fluidic information transmission channel having a manifold 20, pulsator 22, and pulser 24. The stems are flexibly suspended from frame members and supported on recessed cradles 40, 42. Code bars 45 to 92 as described e.g. in Specification 1,159,474 are disposed adjacent the underside of the tube to be lifted in unique combinations by individual typewriter keys, code recesses being arranged in the top of each code bar in a unique permutation corresponding to the associated key. An array of 8 valves each has an associated fluidic transmission channel, and depression of each typewriter key vents a unique channel combination, decoupling corresponding pulsaters 22 from pulsers 24 and operating a tape punch as described e.g. in Specification 1,059,625. Lifting of the tube by a code bar (Fig. 2, not shown) flexes the suspensions and springs, so that the turns of the latter open. In a modification, the cradles are eliminated and the tube may be deflected in two perpendicular directions by corresponding sets of code bars. The suspenders may be rigid and pivoted, while member 10 may be solid and stem 15 may be tubular with corresponding connecting tubing. Alternatively stem 15 and member 10 may be solid, in which case one spring only acts as a valve. Reference has been directed by the Comptroller to Specification 1,077,972.

Title: Improvements in and relating to devices for cutting sheet metal strips
IPC: B21D43/28
Filed: 1963-07-15
Abstract: 1,037,559. Shearing. SCHLOEMANN A.G. July 15, 1963 [July 28, 1962], No. 27889/63. Heading B3W. An apparatus for dividing sheet metal strip into correctly dimensioned commercial lengths comprises a shear, a roller table and a carriage adapted to grip the strip and to move along the roller table and is characterized in that an impulse generator is associated with the carriage and is connected to a counter which is connected with means for interrupting drive means for the strip when a number of impulses corresponding to a desired length have been counted. The apparatus includes a shear 1, a roller table 12 in front of the shear, a roller table 6 behind the shear, a temperature measuring device 5, and a hold-down 4, Fig. 2 (not shown). An electromagnetic or fluid-operated clamp 7 is mounted on a carriage 8 which has drive means 18a co-operating with a toothed rack 16a and an impulse generator 28a. A similar clamp 20 and carriage 17 which carries a limit switch 24 traverse the roller table 12, the rolls of which are driven individually by motors 13, which are connected to a control device 27 and operate simultaneously with the drive means 18a. Strip to be divided is gripped by the clamp 20 and moved into the shear for the waste end to be cropped. An impulse generator 28 on the carriage 17 is then switched on a feeds impulses to a counter 30 and hence to a calculator 21. The length to be cut is pre-set on a device 34. As the strip passes through the shear, the device 5 measures its temperature and transmits the information to the calculator 21 which allows for expansion corresponding to the desired cutting length. The calculator 21 then stops the drive to the carriage 17 and the motors 13 are either stopped simultaneously or after a slight delay. The clamp 17 holds the strip during the cutting operation, and the cycle of operations is repeated until the leading end of the last length to be cut has passed through the shear. At this point the carriage 17 and table 12 are stopped, the clamp 7 grips the strip and the drive means 18a starts, and at the same time the clamp 20 is opened and the carriage 17 returns along the table 12 towards the next new length of strip. The impulse generator 28a now feeds impulses to the counter 30 and calculator 21 which stops the last sheet for the waste end to be cropped. In a modification, the carriage 8a is moved a predetermined distance by a fluidoperated cylinder 10a, after the clamp 7 has closed.

Title: Improvements in or relating to radio systems for determining direction for navigation purposes
IPC: G01S1/02
Filed: 1947-10-21
Abstract: 669,303. Radio navigation. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Oct. 21, 1947 [Jan. 22, 1942], No. 28144/47. Class 40 (vii). In a radio beacon system in which a transmitter radiates a carrier signal from one aerial and side-band signals derived by modulating and suppressing the carrier from a second spaced aerial so as to establish an azimuthdependent phase displacement between the carrier and side-band signals, a receiver ascertains its azimuth from the transmitter by an indication which is a function of both the amplitude modulation and the phase modulation of the radiated field. It is shown that the depth of the amplitude modulation is proportional to the cosine of the phase displacement and the depth of the phase modulation proportional to the sine of the phase displacement. Thus in one arrangement, the phase displacement and hence the azimuth angle upon which it depends may be obtained by comparing readings from separate amplitude- and phaseresponsive detectors. In a preferred arrangement, Fig. 3, employing a single instrument giving a direct reading, the carrier and sidebands pass through receiver 3 to filters 5 and 51 which split the signals into carrier plus lower side-band in the one case and carrier plus upper side-band in the other case. The filter outputs are combined additively by transformer windings 6, 61 for application to a stator coil 9 and subtracted by windings 7, 71 for application to a stator coil 10. Block 8 comprises a delay means for causing a phase shift of 90 degrees in the modulation of the signal applied to coil 10. The rotatable search coil 11 feeds an amplitude detector 12 and telephones 13. It is shown that the modulation disappears from the telephones when the angle # made by the coil equals the phase displacement angle. The system may be employed to mark a course by setting the coil at a desired angle and moving the vehicle in which the receiver is installed such that a null indication is maintained. Specification 491,963 and 571,239 are referred to.

Title: Electrical accumulators
IPC: H01M10/26
Filed: 1966-06-24
Abstract: 1,143,353. Accumulators. W. GREUTERT. 24 June, 1966 [8 July, 1965], No. 28407/66. Heading H1B.  An accumulator comprises a metallic positive electrode comprising a metal or a metalloid, a negative electrode which when charged comprises an alkali or alkaline earth metal amalgam and a basic electrolyte containing reactive anions which during charging interact with the metal of the positive electrode, or the reaction products formed at the positive electrode during charging, to produce soluble metallic anions containing said metal or metalloid. The positive electrode may contain Hg, Fe, Co, Ni, Zn or Cd, As, Sb, Sn, Cr or an alloy, e.g. a Co/Ni, Cu/ Zn or Cu/Sn alloy, the metals of the alloy having similar solution and separation potentials. It may be a multilayer structure having, for example, layers of Ag and Ni or Ag and Cd or comprise a core of a noble metal, e.g. Ag, Cu or an inert material, e.g. magnetite or graphite and an outer coating of As, Sb, Sn, Ni or cobalt. The metal of the positive electrode may be fully dissolved when the accumulator is completely charged. The electrolyte may be an aqueous solution of KOH, NaOH or LiOH, e.g. a saturated solution in equilibrium with some solid hydroxide. It may contain sulphide ions. The reactive ion may be cyanide, rhodamide, formate, acetate, propionate, oxalate, tartrate, citrate, hydroxide, an anion containing a polyvalent metal, e.g. permanganate, nitrate, pyrophosphate, halide or an ion of a derivative of H 2 SO 4 . A stoichiometric deficiency of reactive ion may be used so that when this is exhausted insoluble material is formed on the positive electrode and charging automatically ceases. This may be achieved by using a mercury positive electrode, a negative electrode containing 5 times the weight of mercury and a quantity of iodine as complexing agent which is about 3 times the weight of the positive electrode. The electrolyte may be agitated. It may be divided into two compartments by a membrane through which the simple ions may pass, but the metallic ones may not, thus preventing the metallic ions from discharging themselves at the negative electrode. The positive compartment may be larger than the negative compartment, e.g. the membrane may be in contact with the negative electrode.
